sTRIr-ArrLYme ATTACHMENT FOB TIR -BUILDING MACHINES.

Application and September 14, 1926. Serial No. 135,325.

My presentinvention relates to improvements in the building machines andmore particularly to means to be embodied in or attached to suchmachines for applying side o1chafing strips to the tire carcass in thplied-to the sides of the tire carcass.

The said invention inchidesthe novel construction hereinafter describedand defined by the appended claims.

11 embodiment of my invention is illus- H trated in the accompanyingdrawings in which s s Figure 1 is a plan view showing a portion of theframe and core with carcass thereon (conventionally) of a tirebuildingmachine with my attachment applied thereto.

v Referring by reference characters to these. drawings the letter Aindicates a portion of the frame of a tire building machine and B thecore designed to be rotatably mounted and driven by the usual meanswhile the fabric constituting the tire carcass C is applied thereto byinstrumentalities and in the, manner well known to those skilled in theart and not described or illustrated herein as'unnecessary for anunderstanding of the present invention.

My attachment comprises a carriage or frame mounted to move in arectilinear. path perpendicular to the plane of he core and intersectingsuch plane outside the periphery of the core, and such carriagepreferably rigi ly connected by cross pieces 3, l, pinned orotherwisesecured to the rods so as to hold the. latter against rotarymovement. Secured to the frame A of the machine are a pair of brackets 5and 6 mountedtwo pairs of grooved Whee1s'7, 8", and9, 10 respectively,the grooves of which comprises a pair of parallel rods 1' and 2 CHARLESw; STEELE, or AKRON, onIo, assrenoa To THE MILLER RUBBER comralvv, a V

on which are correspond in shape to the rods 1 and 2, the

upper rod 1 traveling. in and being supported by'the wheels or pulleys 7and'9 while the;

lower rod is guided and 'positioned by the grooves of the pulleys 8 and10.

Rod 1 is extended beyond the cross or connectlng member 3 and hasarticulated to said extended enda bracket 11, having lugs 11, saidbracket being held a ainst longitudinal movement on: the rod hy'collars'1 and 1 pinned thereon. V

' The bracket 11 carries a stud 12 on which is articulated an angular orbent arm 13, the portion of which adjacent the stud 12 is designed toabut against either one of two studs 11 disposed-on opposite sides ofthe stud 12 so as to permit a movement'of the bent arm 13 through an arcof 180 but llmlt its movement in either directionfthe arm at such limitslying in a horizontal plane. Thefiportion 13" of the arm 13 is extendedsu ciently to lie along side the" tire. V i

Mounted on the extended portion 13 of this bent arm is the stri guidingand applying means which' is s own in detail in Figures 3 to 6inclusive.

This comprises a frame member 14 secured to armor rod 13 by a set screw14? which frame carries guides 15 and 16 for the fabric strips whichguides are duplicates of each other;

The frame also carries at one'side, mid} way ofthe guides, an applyinroller 17, and on the opposite side and similarly posi tioned, a guideroller 18., Both rollers are idle rollers and. roller '17" is designedto be rotated by the tire and is shaped to conform 15 with its endprojecting over the roller 17. The opposite end of the strip hangs overthe roller 18. The operator then forces the device in contact with thetire carcass whichis revolving. The strip of material will be fedthrough the guide and drawn on to the tire, being rolled in place by theroller 17.

The arm 13 is then swungv to its opposite position, the rods 1 and 2being slid in their respective guides to such a point that the stripguide approaches the tire carcass on the opposite side. In thisposition. the guide 16 will be uppermost .and the strip to be applied tothe right side of the tire will then be entered through this guide andapplied as before. p i

The rods land 2 are provided with stop collars 19 and 20 which may belocked thereto by set screws not shown. These are for'the purpose oflimiting the motion of the rods 1 and 2 so that the strip guide cannotbe moved farther away from the carcass in. a horizontal direction thanjust out of contact with the tire carcass.

Itwill be understood that in moving the strip guide from the left sideot the tire, as shown inFig. 1 to a position on the right side of thetire, theblock 11 may be rotated around rod 1 a suflicient distance toallow the arm 1.3, carrying the strip guide, to passthe carcass to theother side oi. the tire, and when the arm 13 is moved to the horizontalposition as shown, one Of the, lugs 11 on the block 11 will engage thestop pin 21 and prevent the strip guide "from falling belowthehorizontal plane of the axis of the tire. i

In this connection it will be noted that the stop pin 21 is rigidlymounted on part 3, and the two. lugs ll on part 11 are so located thatin one position of the part 11, one of the lugs 11 contacts with thispin 21 and holds the arm 13 in a horizontal plane, whereas when theother lug contacts with the pin, arm 13 extends somewhat back of thevertical position and out or the way of the tire, so that the tire maybe removed from the machine or other operations-performed thereon.

The guides 15 and 16 are made adjustable to accommodate strips ofdifferent widths by means of the set screws '15 and 16 passing throughslots in the two part guide members as shown clearly in Fig. (3.
